Recognize safety information. This is the safety--alert symbol . When you see this symbol on the equipment and in the instruction manual, be alert to the potential for personal injury. Understand the signal words DANGER, WARNING,andCAUTION.These words are used with the safety--alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies a hazard which could result in personal injury or death. CAUTION is used to identify unsafe practices which may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation. 1 INTRODUCTION Carrier’s 7--day, 5/2--day, 1--day programmable and non--programmable Performance Series Thermidistat Control is a wall--mounted, low--voltage control which combines temperature and humidity control in either a single unit or a two--piece unit. In two--piece configuration, the relays are located near the equipment and a two--wire connection is used between the Display Module and the Equipment Control Module. Single--piece installation requires more wiring and results in a higher profile. The Edger Thermidistat has no need for batteries to store user--configured settings in memory. During power loss its internal memory saves settings for unlimited time, and the clock continues to run for at least 24 hours. An extension of Carrier’s proven line of thermostats; it provides separate setpoints for heating and cooling in addition to humidification and dehumidification. In the Edge Thermidistat Control programmable configuration, different heating and cooling setpoints and times are programmable for 4 periods per day or 2 periods per day. Programming can be done for 7 days per week, 5/2 days per week, or 1 day. The programmable Thermidistat Control can also be user configured as a non--programmable Thermidistat Control. When operating as non--programmable, the Edge Thermidistat Control will still have both temperature and humidity control. The non--programmable Thermidistat Control features Touch ’N’ Got settings for quick and easy temperature change without complicated programming schedules. The non--programmable Edge Thermidistat Control will still have both temperature and humidity control. And, its Touch ’N’ Go technology enables the user to switch between three different user--configurable settings through intuitive buttons located just below the display. 2 INSTALLATION CONSIDERATIONS Power This control is powered by 24VAC only. It requires 24VAC (Rh and/or Rc and C terminals) of the low--voltage transformer to be connected to it for proper operation. It will not operate without these 2 connections. Rh and Rc are connected via PCB breakout jumper. See Fig. 1. For applications using two 24VAC transformers, one in the indoor unit and one in the outdoor unit, connect the common from each to the C terminal. Connect R from the indoor unit to the Rh terminal. Connect R from the outdoor unit to the Rc terminal. Then, break jumper on the circuit board. The W and HUM signals are taken from the Rh power and the G signal is taken from the Rc power. If Thermidistat Control has been installed in a two--transformer application that is later changed to a single--transformer installation, installer must install a field supplied jumper between Rc and Rh. Depending on the installation, up to 14 wires may be required. Installation as two--piece unit is recommended. Only 2 wires are required for connection between Display Module and Equipment Control Module. These two wires (V+ and Vg) do not provide ordinary 24VAC. They carry a combination of power and communications data that is unique to these products. 3 A07052 Fig. 1 -- PCB Breakout Jumper Models There are programmable and non--programmable models for all applications. They can be configured for AC or HP, 1--or 2--speed compressor, and for Hybrid Heatt installations, allowing it to be used in place of all Carrier thermostats. Programmable Thermidistat Controls may be configured as non--programmable if user desires. Humidify Equipment and Connections The humidify output connects directly to 24VAC operated humidifiers. An isolation relay may be required when using powered humidifiers. No other connection or interlock is required. Any of several installer--selectable operating modes are available. 4 ! WARNING ELECTRICAL OPERATION HAZARD Failure to follow this warning could result in personal injury or death. DO NOT connect furnace HUM terminal directly to Thermidistat Control HUM terminal. This will bypass furnace safety controls. See Low Voltage Wiring Diagrams and notes for proper connection. Dehumidify Equipment and Connections The dry contact output connects to the dehumidify input on variable--speed furnaces and fan coils. Additional dehumidification is done by controlling the compressor. A variety of operating modes are available. The dry contact must be configured for dehumidification in setup Option 19. See Wiring Diagrams for more information. Outdoor Temperature Sensor (TSTATCCSEN01--B) Outdoor air temperature sensor is included in the box with the Thermidistat Control. Optimum performance is obtained when an outdoor temperature sensor is used with the Thermidistat Control. Plan installation so that 2 wires can be run from Equipment Control Module to an outdoor location, preferably on the north side of the house or refer to Installation Instructions included with the outdoor temperature sensor for simplified connection. Sensor can be mounted to outdoor unit and existing control wires may be used for its connection. Details are provided in sensor instructions. 5 Remote Indoor Temperature Sensor A remote temperature sensor may be used with the programmable model, where it is desirable to install the Thermidistat Control in a limited access location while measuring the temperature in the living space. The remote room sensor may be used as a stand alone or average with local sensor. Two--Piece Thermidistat Control Configuration The Performance Series Thermidistat Control can be installed in one of two configurations. The control may be installed as a single--piece Thermidistat Control or it may be split into two pieces and mounted in separate locations. As a single--piece unit, all required wiring must be brought to the Equipment Control Module for connection to the terminal strip. In two--piece configuration, the Display Module can be mounted in the living space while the Equipment Control Module may be mounted near the indoor furnace or fan coil. Connection from the Display Module to the Equipment Control Module requires only two wires. All other control wires are connected to the Equipment Control Module from the HVAC equipment. This configuration results in a slimmer display and locates the Equipment Control Module containing the switching relays away from the main living space where relay clicking will not be heard. The model numbers on the Display Module and the Equipment Control Module (ECM) must match or unpredictable results may occur. Two--wire pigtail replacement part number is TX--2WR05. Wiring For all wiring applications, use 22 AWG or larger wire. Continuous wire lengths over 100 ft. (30.5 m) should use 20 AWG or larger. Wire lengths are not to exceed 250ft.(76m)perrun. 6 INSTALLATION ! CAUTION UNIT DAMAGE HAZARD Failure to follow the recommended wiring practices could result in damage to the wall control and personal property. Improper wiring or installation may damage Thermidistat Control. Check to make sure wiring is correct before proceeding with installation or turning on power. Installation Notes: S No part of the control should be installed directly outdoors or in a cabin- et outdoors. S Never remove the thermostat board from the plastic housing. Doing so could warp and damage the components on the board. S The control assembly should be mounted before wires are attached. S During thermostat installation, provide sufficient excess wiring behind the mounting plate. Coil the wiring, creating a service loop, and place in mounting box or behind the wall to remove strain against the terminal strip.

E-Stop Pushbuttons . Cable-Pull Switches . Two-Hand Controls . Safety Mats . Safety Edges . Signals for Safe Speeds and Standstill Monitoring Safety Controllers Courtesy of Steven Engineering, Inc. - (800) 258-9200 - [email protected] - www.stevenengineering.com Schmersal Safety Controllers What are Safety Controllers? Safety controllers are connected between machine guarding devices such as keyed interlocks, non-contact sensors, light curtains, etc. and the machine’s stop control elements such as a motor contactor or control relay. These controllers contain redundant, self-checking monitoring circuits and positive-guided relays and/or solid state outputs. Each is designed to detect faults in the safety system’s components and interconnection wiring, and their own internal monitoring circuits and output. Detection of a fault, or of an open machine guard, disables the controller’s output signal(s) facilitating machine stoppage, and/or prevents the restarting of the machine until the fault has been corrected. Units are available for use with guard interlock switches, coded-magnet sensors, safety edges, two-hand controls, light curtains, E-stops and emergency cable-pull switches to satisfy a broad range of application requirements. What are their functions? In addition to detecting open guards and/or actuated safety input devices, safety controllers are capable of detecting the following types of safety system faults: guard monitoring switch/sensor failure, “open-circuit” in interconnection wiring, “short-circuit” in interconnection wiring, “short-to-ground” in interconnection wiring, “cross-short” between channels, welded contact in controlled output device (such as positive-guided motor contactor), failure of safety controller’s positive-guided relay(s), fault in safety system monitoring circuit, and insufficient operating voltage.

  • Time Delay Relays – Application Data
    Time Delay Relays – Application Data Definition: Time Delay is defined as the controlled period between the functioning of two events. A Time Delay relay is a combination of an electromechanical output relay and a control circuit. The control circuit is comprised of solid state components and timing circuits that control operation of the relay and timing range. Typical time delay functions include On-Delay, Repeat cycle (starting off), Interval, Off-Delay, Retriggerable One Shot, Repeat cycle (starting on), Pulse Generator, One Shot, On/Off Delay, and Memory Latch. Each function is explained in the table below. Time delay relays have a broad choice of timing ranges from less than one second to many days. There are many choices of timing adjustments from calibrated external knobs, DIP switches, thumbwheel switches, or recessed potentiometer. The output contacts on the electromechanical output relay are direct wired to the output terminals. The contact load ratings are specified for each specific type of time delay relay. Understanding the differences between all the functions available in time delay relays can sometimes be a daunting task. When designing circuits using time delay relays questions such as: “What initiates a time delay relay?” “Does the timing start with the application or release of voltage?” “When does the output relay come on?” must be asked. Time delay relays are simply control relays with a time delay built in. Their purpose is to control an event based on time. The difference between relays and time delay relays is when the output contacts open & close: on a control relay, it happens when voltage is applied and removed from the coil; on time delay relays, the contacts will open or close before or after a pre-selected, timed interval.

The main fault with the explosion-proof system is that a single human error could create a high explosion probability. Prime examples are failing to tightly replace covers on explosion-proof housings, failing to shut off the power before removing the covers, and damaging the specially machined surfaces of these covers. Intrinsically safe (IS) systems are a means of providing automated control functions in explosive environments. Because of the inherent parameters of electronic circuits, no energy is released, under normal or abnormal conditions, of sufficient magnitude to ignite a specified atmosphere mixture. To design an effective intrinsically safe system, energy that enters the hazardous area must be limited. For electronic instrumentation, this is accomplished by controlling the voltages and currents that may enter the hazardous area. In addition, stored electrical energy in field instruments is limited to levels that cannot ignite a given atmosphere. Intrinsically safe relays, such as the NY2 and the Class 8501 Type TO relays, act as an energy barrier, limiting the voltage and current available in the hazardous area. They can be connected with any device having a dry contact (limit switch, magnetic switch, pushbutton, pneumatic-electric interfaces, etc.) or with NAMUR sensors.

  • A Dry Contact Is a Potential Free Contact a Dry Contact Is a Contact That Does
    A dry contact is a potential free contact A dry contact is a contact that does not provide voltage. For instance, the push-to-talk switch of a microphone, which just closes a circuit without providing voltage. A wet contact is a contact that will provide voltage when closed, like the switch on the wall that activates the 110 VAC outlet to turn a lamp on in a room. Potential free contact, voltage free contact and dry contact, they all are same. The dry contact is the contact which is physically operated with the main device, but not electrically connected to it. It is a voltage free on/off contact and can be used in any system. The auxiliary contact of the motor contactor used for the motor run feed back is the example of the dry contact. The contacts of the interposing relays are also dry contacts. - MS Perhaps you mean "dry circuit"? Contacts which need to work in such circuits are generally gold-plated, since the current and voltage levels are too low to break down the contaminant layWhat is a volt free contact? Answer: A volt free contact is a set of contacts that uses a voltage source from another location. The contacts are used to tie two individual pieces of electrical equipment together so the action on one will cause the other piece of equipment to operate. It is just a new way of using the older terminology "dry contacts". An example of use is the diesel start contacts on an automatic transfer switch. When the transfer switch is in the utility (hydro) position the diesel start "dry contacts" located in the transfer switch are open.

  • Time Delay Relays
    TIME DELAY RELAYS Definition of Timing Functions Understanding the differences between all the functions available in time delay relays can sometimes be a daunting task. To begin with, time delay relays are simply control relays with a time delay built in. Their purpose is to control an event based on time. Typically, time delay relays are initiated or triggered by one of two methods: u application of input voltage (On Delay, Interval On, Flasher, Repeat Cycle & Delayed Interval) u opening or closing of a trigger signal (Off Delay, Single Shot, Watchdog & Triggered Delayed Interval) These trigger signals can be one of two designs: a control switch (dry contact), i.e., limit switch, push button, float switch, etc., or by voltage (commonly known as a power trigger). To help understand, some definitions are important: u Input Voltage - control voltage applied to the input terminals. Depending on the function, input voltage will either initiate the unit or make it ready to initiate when a trigger signal is applied. u Trigger Signal - on certain timing functions, a trigger signal is used to initiate the unit after input voltage has been applied. As noted above, this trigger signal can either be a control switch (dry contact switch) or a power trigger (voltage). u Output (Load) - every time delay relay has an internal relay (usually mechanical) with contacts that open & close to control the load. They are represented by the dotted lines in the wiring diagrams. Note that the user must provide the voltage to power the load being switched by the output contacts of the time delay relay.
